' Application tiled November 24, 1905. Serial No. 288.965-

To Iall whom it may concern: I

Be itknown that I, CALEB STEVENS GUE- NEY, a citizen of the UnitedStates, residing at Portsmouth, in the county of Rockingham and State ofNew Hampshire, have invented certain new and useful Improvements inUmbrellas; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements 1n umbrellas; and it consists incertain novel.

4use and less expensive to manufacture.

The above and other objects which will appear as the nature of theinvention is better understood are accomplished by means of theconstruction illustrated in the accompanying drawings, in which- Figure1 is a sectional view through a frame of Ian umbrella embodying myinvention. Fig. 2 is a sectional view, on an enlarged scale, through thefastening member for the inner ends of the ribs. Figs 3 is a similarview through the runner. Fi s. 4 and 5 are views of the inner oropposing aces of the disks between which the ribs and braces orstretchers are pivoted. Fig. 6 is a perspective view, on a'n enlargedscale, of one end of one of the ribs or stretchers, showing the mannerin which its pivot-tip is secured; and Fi s. 7 and 8 are respectivelylongitudinal an transverse sectional views through.

the rib and its tip.

Referring to the drawings by numerals, 1

denotes the rod or staff of an umbrella which has adjacent to its upperor outer end a fastening member or head 2, in which the upper ends ofthe ribs 3 are pivoted, and slidable upon this central portion is arunner 4, to'

which the lower or inner ends of the braces or stretchers 5 aresimilarly pivoted. The braces or stretchers 5 are pivotally connected tothe ribs 3 in the manner shown or in any lother suitable or preferredWay.

The fastening member or head 2 comprises a sleeve or tubular element 6,which is fixed upon the rod 1 in any desired manner, and has -its lowerend externally screw-threaded,

ment of the tip in the rib or' stretcher.

as shown at .7. Formed or provided upon the sleeve 6, intermediate itsends, is a disk 8,which has in its` face, adjacent to the screw-threads7, semispherical sockets 9-, which have contracted Vportions 10,extendin radiall and openin in the eri he of thi said disk 8. g p P rypivoted between the sockets 9 andsimilar semispherical sockets 1 1,formedin a removable disk 12, which has a central opening through whichthe threaded portion of the The ends of the ribs `3 are l sleeve 6extends. This disk 12 is adapted to be clamped u on the disk 8 by meansof a nut 13, whic isengaged with the screwthreads 7, and in itsperiphery is formed a series of radially-extending notches or' slots 14,which aline with the sockets 11 and with the neck portions -of thesockets 9.

The construction of' the'runner 4 is very similar.. It comprises a longsleeve or tube 15 which slides upon the rod 1 and is formed with alongitudinal slot 16 to 'engage the usual spring catches or kee ers uponthe rod.

The inner or upper end o the sleeve 15 is screw-threaded, as shown at17, and formed or secured u on it adjacent to said screwthreads is a isk18, which is similar to the disk 8. Said disk 18 has the semicircularsockets 9, which have thecontracted neck portions 10. Clamped upon the,disk 18 by means of a nut 19, which engages the screwthreads 17 is adisk 20, which is similar to the disk 12. Said disk 20 is formed withthe semispherical sockets 11 and the radial notches or slots 14.

The pivots or balls upon the inner ends of g the ribs 3 and stretchersor braces 5 are the same and each comprises a solid tip 22, which isstraight and of cylindrical form and adapted to have one of its endssecured within the end'of the rib or stretcher and its other 'end seatedin a pair of sockets 9 11. The ribs 3 and stretchers 5 are preferably inthe form of channel metal, LI-shaped or para-y gon shape incross-section, and the tips 22 are secured in their ends by clasping,compressing, and indenting these parts, as shown at 23, so that portionsof the flanges of thev ribs or stretchers will enter depressions orrecesses formed in the body of the tip, as clearly shown in Figs. 6 and7. This manner of fastening the tips is extremely durable and4inexpensive and effectively prevents both longitudinal and transverse oraxial move- The outer end of each of the tips 22 is formed IlO' ' with aball` or sgherical head 24, which is adapted to seat 11, and adjacent tosaid ball or spherical head the tip is formed with a flattened portion25, which is adapted to project throu h and swing inthe notches or slots14 and t e contracted neckportions .of the sockets 9. This flattenedportion of the tip is preferably formed by compressing the same atdiametrically opposite points, as clearly shown in Figs. 6 and 7.

The `construction andadvantages of the invention will be readilyunderstood from the foregoing description, taken in connection with theaccompanying .drawings It will be seen that the construction is sim le,strong, and durable, so that the umbre las may be manufactured atcomparatively s mall cost. The provision of the nuts 13 and 19 permitsthe disks 12 and 2O to be readily removed, so that new ribs may beprovided,

to replace broken ones. The provision ofthe flattened portions 25 Qn thepivot-tips 22 effectively prevents the balls or spheres 24 from turningor twisting ire-their sockets, and

.. by clasping, compressing, and indenting the longitudinal and axialmovement, by clasping and compressing the same to form indentures ordepressions, substantially as shown and described.

2. In combination with a rib or spreader having a pivotal element at oneend, an umbrella-notch comprising an inner element and an outer elementformed 1n their o posing faces with rib or stretcher pivota elementreceiving'sockets, the inner element being also provided with radialslots extending outwardly from s'aid sockets to clear the etwcen thesockets 9 and v d radia ribs orl stretchers when the .umbrella isclosed, the outer element being also provided in' its inner side withradial neck-grooves extending outwardly from the said sockets toreceivethe ribs orstretchers when the umbrella is opened and preventlateral turnin of said ribs or stretcher with respect to sai umbrellarod or handle, substantially 'as described.

3. In an umbrella, the combination of a tubular element or sleeve,external screwthreads at oneend of said element, 'a disk upon saidelement intermediate its ends and having in its face, adjacent to saidscrewtlireads semis herical sockets formed with contracted nec portions,a removable disk upon said element havin in its inner facesemislpherical sockets an in its periphery v-extendin vnotches or slotswhich aline vi ith said socets, a nut upon 'the screwthreaded end ofsaid element for clampingv said disks together, and ribs or stretchershaving balls at their ends to enter said sockets and flattened portionsadjacent to said balls, to profeet through and swing in said iotches ors ots and in said contracted neck portions of said sockets,substantially as described.

4. In combination with a rib or stretcher having a ball at one end, anumbrella-notch comprising an inner element and an outer element; saidelements formed in their opposing faces With ball-receiv ng sockets, theinner element being also provided with a radial slot extending outwardlyfrom the ballreceiving socket to clear the rib or stretcher when theumbrella is closed, the outer element being also provided on its innersideA with a radial neck-groove extending outwardly from theball-receiving socket to re- 4 ceive the rib or stretcher, when theumbrella is opened and prevent lateral turning of said rib or stretcherwith respect to the umbrella rod or handle. f

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses; l
